Customer Review: “This gas tank fit perfectly. I bought it for a Troy built TB110 140cc mower with a Briggs and Stratton. Came with plenty of fuel hose and clamps. The fuel cap retention is on the outside, which is better than factory for access. Good cap and seal. I was very surprised.”
Customer Review: “I purchased this product as a replacement for the fuel tank on a TroyBilt TB110 mower with the 550EX engine.

Mower was starving for fuel but the pin hole has helped it function properly!”

Customer Reviews
Customer Review: “Some critter chewed through the corner of the old tank… This tank is the replacement for the original which had the cap on the left instead of the center. So just trimmed the red engine shroud and if fit perfectly. Included hose was a little short so I just used the old one and cut that down about an inch. Hopefully whatever chewed the old one doesn’t like this new plastic…”
Customer Review: “Why did you pick this product vs others?:This product is not compatible with the part numbers listed. It will fit the application but will not work. The product pictures curiously omit the inside of the gas tank and the backside of the gas cap. These are very important because they do not match the original product. The gas can has a white plastic/metal mesh gasoline filter inside and the gas cap is not pressurized on this product and does not vent the same was as the original. The design of the gas filtration system and the air/vacuum system are different than the manufacturer’s intentions and did not work or my Toro B&S lawnmower. Once I installed the new tank, my mower would start and immediately shut off. I bought a new air filter, spark plug and even starter fluid all to no avail. I then removed and cleaned the carb and it started and ran for a minute before turning off again. Eventually, I bought the OEM part which costs the same and is also available on Amazon (https://www.amazon.com/dp/B089LJYMQ9?ref=ppx_yo2ov_dt_b_fed_asin_title). The OEM part went in and the mower runs flawlessly. By way of background, the mower was only 2 years old and needed a gas can because the squirrels ate through the original one. This is also the first review I have ever written despite purchasing on Amazon for for over a decade. Sooooo upset I was duped and unable to get a refund after wasting all that time and effort needlessly. Save yourself the headache and get the OEM part.”

Complete Buying Guide for Best Gas For Mower
Essential Factors We Consider
When choosing the best gas for your mower, we look at a few key things. First, is the fuel type compatible with your engine? Most walk-behind mowers use regular unleaded gasoline, but older or specialized engines might require something different. We also consider fuel stabilizers and additives, as they can significantly extend the life of both your fuel and your engine, especially if your mower sits for extended periods. Durability of the fuel tank itself is paramount; we prioritize tanks made from robust, fuel-resistant materials that can withstand constant use and varying weather conditions. For those with larger properties, such as those considering a riding mower for 5 acres, tank capacity and ease of refueling also become critical factors.
Budget Planning
The cost of fuel and replacement parts can add up. For routine maintenance like refueling, using a good quality, standard unleaded gasoline is usually the most cost-effective. When it comes to replacement fuel tanks or fuel additives, the initial investment can seem higher, but it often pays off in the long run. A durable fuel tank, for example, can prevent costly repairs down the line. Using a fuel stabilizer can prevent fuel from degrading, saving you from potential engine issues and the need for more expensive repairs. Consider the longevity and performance benefits when evaluating the price.
Final Thoughts
Selecting the right fuel and a dependable fuel tank for your mower isn’t just about keeping it running; it’s about ensuring its longevity and efficiency. Whether you’re managing a small suburban lawn or a sprawling acreage, the fuel system is the heart of your mower. By choosing quality components and the right fuel, you’re investing in reliable performance and fewer headaches. For those tackling tougher jobs or larger areas, understanding how your mower handles different terrains, like hills which require a specialized lawn mower for hills, or thick grass, is also important.
Frequently Asked Questions
Q: What type of gas should I use in my lawn mower?
A: Most lawn mowers typically use regular unleaded gasoline with an octane rating of 87. Always check your mower’s owner’s manual for specific recommendations. It’s generally advised to avoid gasoline with ethanol content higher than 10% (E10) as it can damage fuel system components over time.
Q: How often should I change the fuel in my lawn mower?
A: If your mower sits for more than 30 days, it’s best to use a fuel stabilizer. For storage over the winter, drain the fuel tank or fill it completely with stabilized fuel to prevent condensation and degradation. Fresh fuel should be used at the start of each mowing season.
Q: Can I use old gas in my lawn mower?
A: It’s not recommended. Old gas can degrade and form gum or varnish, which can clog fuel lines and carburetors, leading to starting problems and poor engine performance. If you must use older gas, consider adding a fuel stabilizer to help mitigate some of the negative effects.
Q: What if my lawn mower tank is leaking?
A: A leaking fuel tank is a serious safety hazard. You should stop using the mower immediately and replace the fuel tank. The products reviewed here are designed to be direct replacements for common mower fuel tanks.
Q: How do I know if I need a new fuel tank?
A: Signs you might need a new fuel tank include visible cracks or damage, fuel leaks, difficulty starting the mower, or a persistent smell of gasoline. If the fuel cap isn’t sealing properly or the tank appears corroded, replacement is likely needed.
Choosing the right gas and ensuring your fuel system is in top condition is vital for a healthy, happy lawn mower. Whether you’re dealing with a simple fuel leak or looking for the best way to store fuel, the right components make all the difference. Remember to always consult your owner’s manual and consider the specific needs of your mower and lawn, especially if you’re navigating challenging conditions like thick grass, which might require a lawn mower for thick grass. Happy mowing!
